error in interceptor: InputStreamCache cannot be cast to org.w3c.dom.Node
Hello all, I am implementing a monitor on my routes, using an interceptor. I am using Camel 2.3.0 inside Servicemix 3.3.2. The routes are working ok without the interceptor. In the monitor, I try to log the message, but it seems (not sure about this, just a guess) that that is causing the InputStream to be read and then It seems that it can not be read again. I am already using getContext().setStreamCaching(true); in my routes. Below, you can see the stack trace, any comments or help on this will be welcome. Thank you in advance. Javier Arias.

Re: error in interceptor: InputStreamCache cannot be cast to org.w3c.dom.Node
In your custom interceptor, then you can either - skip any streams (eg do not touch them) - reset the stream cache By resetting the stream cache you should be able to re-read the stram again. There is some code on trunk that does that.
